Place a large skillet over medium heat. Add the oil, ground pork, garlic and ginger. Brown for 5 minutes, breaking into small pieces with a wooden spoon. Then add the mint, soy sauce, fish sauce, lime juice and crushed red pepper. Stir and cook another 3 minutes until the liquid absorbs.
For lettuce wraps: Place a spoonful of the nam sod meat filling in lettuce leaves, then top with veggies and peanuts.
